Product Description:

The MDD090A-N-030-N2M-110PR0 is a synchronous AC motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where inverter current is converted into controlled rotary motion for positioning, tracking, and repetitive cycle tasks in automated equipment. This arrangement supports stable speed regulation and accurate axis response in conveyors, pick-and-place modules, and indexing stations that depend on coordinated motion.

At standstill, the motor can deliver a continuous torque of 3.7 Nm, which indicates the static load it can hold without overheating. During operation it reaches a nominal speed of 3000 rpm, giving the drive a common operating range for dynamic axis movement. Accurate coupling is supported by a centering diameter of 110 mm and standard balancing that helps reduce residual vibration. Power and feedback conductors exit on the right side through a coded connector, which can simplify cable routing in compact machine layouts. The housing is made of standard cast aluminum, and a shaft seal is fitted to help keep oil and dust away from the bearing area.

For feedback, the rotor uses an integrated multiturn absolute encoder that sends position data as digital servo feedback (DSF) to the drive, so axis position remains available after power cycling without a separate homing step. The motor is supplied without a blocking brake, so holding force at a stop must be provided by drive torque or by an external device when the application requires it. Its mechanical interface uses length code A and size 090, and the output shaft has a keyway profile while the second shaft end is omitted to save installation space. This layout suits compact machine sections where axial clearance is limited and direct coupling to pulleys, gears, or couplings is required.
